IMPROVED VISE FOR HOLDING AND SWAGING HORSESHOES.

Speoiiication forming part of Letters Patent No. 34,786, dated March 25, 1862.

tion. Figs. 2, 3, and 4 are perspective views of the dies. Fig. 5 is a perspective view of a horseshoe.

My invention consists in aftixing movable and adjustable dies to the jaws of a vise for swaging and forming the calks of metallic shoes, and in operating a vise and gripping the shoes between the dies by means of a treadle.

To enable others skilled inthe artto make and use my invention, I will proceed to describe its construction and operation.

In Fig. 1, A B is the vise, secured to post X' by bolts C C. D is a treadle hung in a movable joint in the vise at b and passes through a mortise in post X', as indicated by the dotted lines. E is a friction-Wheel affixed in a crutch D' by pin d'. G' G are dies secured to the jaws J J by bolts c' a'. H is a hinge and connects A and B'. I' is the lower end of B', (the movable part of the vise,) bent in the form 4of a curved hook.

In Figs. 2, 3, and 4, A2 A3 A4 are dies. a2 a2 co2 a3 a3 as d4 are bevels designed to form corresponding bevels on the calks. Ca2 a2 a2 in Fig. 2 is an oblique bevel for the swaging of sharp calks. d3 a3 a3 is a form for raising a a4 is a form for smooth calks.

In Fig. 5, y is a horseshoe. x5 x5 @c5 are calks. c5 is a strdng bevel on the inside of the calk.

Operation: The several parts of the shoevise being constructed as herein described, the dies afiixed to the jaws as herein specitied, the vise A' attached to post X by bolts C' C', and post X secured to the anvil-block by bolts F' F', its operation may be noted. When the steel designed to form the calks is welded to the shoe, the shoe is put between the jaws of the vise so that the steel will project over and rest on the die. One foot placed on the treadle at w' will cause the frictionwheel E to travel up the inclined plane formed by the lower end of B', causing the dies to grip the shoe at z5, (see Fig. 5,) when the calks are quickly and accurately swaged by hammering. When the foot is removed from the treadle, the weight of E will cause it to fall and assume the position indicated by the engraving, and the weight of the lower end of B' will cause it to swing in and follow the friction-wheel in its descent until the wheel rests in the curved hook I'.

I do not .confine my invention to swaging the calks of horseshoes. Calks on any metal lic shoe may thus be formed. Neither do I claim any device previously invented or patented for swaging or forming the calks of shoes; but

What I do claim as my invention, and desire to secure by Letters Patent, is

A hinge-vise A B', with movable and adjustable dies G G' affixed to the jaws J' J'., on which to form the calks of shoes, .the treadle D', and friction-wheel E', constructed and operating substantially as and for the purpose set forth and described.
